Apache Ivy

Apache Ivy is a transitive dependency manager. It is a sub-project of the Apache Ant project, with which Ivy works to resolve project dependencies. An external XML file defines project dependencies and lists the resources necessary to build a project. Ivy then resolves and downloads resources from an artifact repository: either a private repository or one publicly available on the Internet.

To some degree, it competes with Apache Maven, which also manages dependencies. However, Maven is a complete build tool, whereas Ivy focuses purely on managing transitive dependencies.

Newer build tools and continuous integration servers regularly support or include Ivy:

sbt, or "simple build tool," the primary build tool for Scala projects, incorporates Ivy for its dependency management.
